Polishing refers to treatments produced in more Superior treatment method techniques immediately after the above mentioned procedures (also referred to as "fourth phase" treatment method).

They can be created by consensus, issue to overview and comment by AWWA committees, councils, and users. Given that they signify AWWA’s posture on these issues, they are accredited through the AWWA Executive Committee with the board of directors.
Source Restoration principles are evolving, and researchers are investigating and developing several systems. Reclamation and reuse of treated water for irrigation, groundwater recharge, or leisure applications are particular regions of emphasis.
